CHURN.

SPECIFICATION forming part of Letters Patent No. 655,871, dated August14, 1900.

Application filed June 4, 1900.

To all whom/it may concern: Be it known that I, ABNER B. JOHNSON, acitizen of the United States,residing at Springfield, in. the county ofGreene and State pf Missouri, have invented certain new and usefulImprovements in Chorus; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and-use thesame.

My invention relates to improvements in churns, the object of which isto provide a churn that will quickly produce butter from milk or cream.

This invention consists in a mechanism for forcing air through the creamwhile it is kept constantly agitated and a device for preventing thecream from rising and overflowing the churn, all fully described,combined, and specified in the claim, the same being illustrated in theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a view giving an elevation of the entire device, a part ofthe churn being removed to show the interior. Fig. 2 is a detail showingthe under side of the dasher.

Similar letters of reference indicate corresponding parts.

A is an ordinary churn of any desired size and shape, having a cover Awith an opening in the center of any desired size for re I ceiving thedasher and air-pipes, said churn also having a cup A in the bottom forre ceiving the lower end of the revolving dasher to form a bearing forthe same. In glass and earthen churns a cross-piece A having a cup;bearing A may be used in the bottom of the churn.

B is a dasher-rod provided with a pointed end bearing 13 at the bottomof a churn and having a pinion B for operating the said dasher by meansof any ordinary power. Said pinion is provided with a sleeve having athumb-screw B for adjusting the same at any desired height. The upperend of said dashershaft B may be provided with any suitable bearing inthe framework which supports the upper or drive wheels. Ois a sleeve onthe said dasher-shaft B, secured in position by means of a thumb-screw 0so that the same may be raised or lowered, as desired, according to thedepth of cream or milk to be churned. On the lower end of said sleeveare secured the cross-dashers D, to the top of which is secured a soliddisk E, having a rim F proof the churn.

Serial No. 19,088. (No model.)

jectin g downward around its periphery. Said rim F is preferably made toextend downward so as to cover about half. of the width of the crossdashers D, the dashers 1D being made of any desired size and length,according to the size of the churn in which they are to be used.

At opposite sides of sleeve C air-tubes G, which are secured to disk E,extend from a desired point above the covers A and through the disk E toa point preferably below the lower edge of the dashers D for conductingair down into the cream as the dashers revolve. Said air pipes or tubesG are provided with suitable dampers or stop-cocks G which may beoperated, by means of thumbpieces G ,'for regulating the quantity of airto enter the cream.

H is a fan for driving or forcing air downward to enter the air-tubes G.Said fan is provided with a sleeve having a set or thumb screw H foradjusting the height of the fan or its distance from the air-tubes toregulate the force of the air to be driven into the mill through theair-tubes G.

This process of churning fills the cream or a milk with air to suchanextent that it would flow over the top of the churn without something tokeep it down. This I provide against by using three or more fan-shapedwheels I. These break the foam-bubbles and prevent the cream fromrunning over the top These fans I are secured to the inner surface ofthe churn A at different heights, so that one or more will be above thesurface of the milk or cream to be churned. They are provided with anaxis I for permitting the said wheels I to revolve for the purpose ofbreaking the air bubbles, as specified.

Having thus described my invention, what .I claim as new, and desire tosecure by Letters 1 Patent, is

The combination of a churn, A, having a S. A. HASELTINE, M. L.HASELTINE.
